.Suc'h supplements are used to bring previously published volumes ,up todate. For example, per: manently bound law bookscontaining annotatedstatutorycodes or digests of judicial decisions are subject to constantlegislative amendment or judicial interpretation. Law publishers meetthis condition by periodically printing supplements whose contentsarearranged and intended for M This invention relatesgenerally torbooksg and 'enipty'coverpocketby means of which the sup-'- plement.isattachiad to the permanent volume.

It is obvious that these' permanent volumes and their supplements, beingrelated by a common subject matter, alsoshouldbe physically asso ciated.Not so apparent, but equally important, the physical connection must besuch that it supplement, and vice-versa. For the same rea- 'son, it isimpossible to have the leaves of both the permanent volume' and itsattached supplement fully open concurrently for joint examination. Thesedifficulties can be overcome only by removing the supplement from itspocket. Such removal, however, defeats a prime object of' an attachablesupplement: the physical association of permanent volume and. supplementso that the latter will not be lost or mi'slaid or the wrong supplementconsulted.

The object of this invention, therefore, is to 1 provide a .book with aremovable supplement wherein the leaves of the permanent volume {can beturned without interfering with the open leaves of its attachedsupplement, and vice-versa. A co-ordinate object. of the invention isthe provision of a book of thistype wherein the permanent volume and itsattached supplement concurrently can be fully open for jointexamination. Other objects and a fuller understanding of my inventionmay be had by referring to the following description and claims, takenin conjunction with the accompanyingdrawing in which:

The back 3 01' the permanent volume'is made wider Y thanthe thickness of its body of leaves 4 in order to-provide aspace'betweenthe'leaves 4 and the '-rear cover 2to receive a removable supplement,the difi'erence in width being substantially equal to the thickness ofthe supplement to beaccommodate'd. The leaves 4 are permanently boundtothe back 3, their boundedges being distributed along the back '3 fromcover I to cover 2 in order to lend support to the back 3.

The 'rear cover 2 has a layer of material 5 secured thereto at itsforward and side edges. This shown infFig. 2, it is of irregular shape,having is-slig'htly smaller in length and width than the the cover arm 9project from a trunk l0 of'the V *ce'ntftheback 3. 1 l

The supplement is formed of a coupling memlayer extends rearwardly to apoint adjacent the back 3' and forms with the inner face of the'rearcover-"2 a pocket'fi' which opensvertically adjaber and a plurality ofleaves 1."

The coupling-member is made of terial whichis stifier than theleaves 1.

one arinfhereinafter called-the tapered arm 8,

. of asize and shape allowing a snug but tern:

porary'insertion into the pocket 6, and having'a second arm which servesas aback cover member for the supplement leaves, and'which ishereinafter called the cover-arm 9 The cover arm 9 rear cover 2ofthe'permanent volume.

It will be noted that the tapered'arm 8. and

coupling member of' the supplement. The

tapered arm 8 is folded backwards under the Fig. 1 is a perspective viewof the permanent volume with its rear cover open, showing the trunk l0.

and above the trunk ID, the fold being made along trunk III, the foldbeing made along the vertical line H which is commonto that arm 8 andthe The cover arm 9 is .folded forward the horizontal line l2 which iscommon to that arm 9 and the trunk ID. The creases alon these lines II,I 20f foldmay be reinforced with tape.

The leaves I of the supplement are slightly shorter and narrower thanthe cover arm 9. These leaves 1 are secured thereto by staples l3 sothat their bottom edges are slightly higher than the horizontal line offold l2 in the coupling member.

The supplement is attached to the book by inserting the tapered arm 8into the cover pocket 6, as shown in Fig. 4. The insertion should bemade so that the horizontal line of fold [2 in the coupling member isslightly below the top of the rear cover 2 of the permanent volume. Thesnug fit of the arm 8 in the pocket 6 will maintain this juxtaposition.

this invention, relative terms have been employed in describing the sizeof the supplement leaves 7, the tapered arm 8, and the cover arm 9;likewise in describing the juxtaposition of the supplement leaves I andcover arm 9 and the juxtaposition of the cover arm 9 and the rear cover2 of the permanent volume. Functionally speaking, these dimensions andjuxtapositions should be such that, after the supplement is inserted inits cover pocket 6, the .supplement, when the cover arm 9 is folded,rests entirely within the confines of the rear cover 2, and thesupplement leaves I, when the cover arm 9 is unfolded, will be projectedto a position where their orbit clears-the orbit of the leaves 4 of thepermanent volume.

The permanent volume and its companion supplement are made ready forjoint use by opening the rear cover 2 and unfolding the cover arm 9 ofthe supplement, as shown in Fig. 4. The supplement leaves I will beprojected outside the rear cover 2 to a position where their orbit willclear the orbit ofthe leaves 4 of the permanent volume. Thus, each setof leaves can be freely turned without interfering with the position ofthe other set and, of course, both sets can remain fully openconcurrently at the desired pages. When the permanent volume andsupplement are not in use, the cover arm 9 is folded back so as to restwithin the confines of the rear cover 2 and the permanent volume is thenclosed in the usual manner. The closure can be made without strainingthe binding of the permanent vol-- ume, since its back 3 is wider thanthe thickness of its leaves 4. The supplement thus fits within and formsa component part of the permanent volume, and yet may be readily removedtherefrom and replaced when desired.

It will be noted that the permanent volume herein described accommodatesits companion supplement in a pocket 6 inside its rear cover 2, whichpocket 6 opens vertically adjacent the back 3. This is the type ofpocket used in conventional pocket supplement books and was selected forparticular description and illustration to demonstrate how readily myinvention can be adapted to existing pocket supplement books. However,the objects of my invention can be fulfilled whether the pocket islocated in the front or rear cover of the book; whether the pocket opensvertically, adjacent one side of a cover or the other; or whether itopens horizontally, adjacent the top or bottom of the cover. A change inthe location of the pocket merely requires a change in the shape andfolds of the coupling member of the supplement.

Furthermore, although the removable supplement described herein makesparticular reference to the type which connects to its companionpermanent volumeby insertion into a cover pocket of the latter, it isunderstood that I have particularized this form of attachment by way ofexample only and that numerous changes in the method of connection andother details of construction may be resorted to without departing fromthe spirit and scope of the invention as hereinafter claimed.

Having thus described my invention, I claim:

1. A book having inside the rear cover a pocket opening sidewaysadjacent the back in combinashaped to fit the cover pocket andprojecting from the left side of the trunk, the upper horizontal borderof, said arm being a continuation of the upper horizontal border of thetrunk, said arm being folded backward along its line of junction withthe trunk and inserted in the cover pocket, the second arm being smallerin length and width than the book cover and projecting from the top ofthe trunk, said second arm being scored along its line of junction withthe trunk, the plurality of leaves being smaller in length and widththan the said second arm and mounted within its confines.

2. A pocket supplement consisting of an oblong trunk, two armsprojecting therefrom, and a plurality of attached leaves, the first armprojecting from a vertical border of the trunk, a horizontal border ofsaid arm being a continuation of the same relative horizontal border ofthe trunk, said arm being folded backwards along its line of junctionwith the trunk, the second arm projecting from the aforementionedhorizontal border of the trunk, said arm being scored along its line ofjunction with the trunk, the plurality of leaves being smaller in lengthand width than the said second arm and mounted within its confines.

3. A pocket supplement consisting of a trunk, an arm projecting from ahorizontal border of the trunk, a second arm projecting from a verticalborder of the trunk, and a plurality of leaves mounted on the secondarm.

4. A pocket supplement cover consisting of a trunk and two armscompletely and permanently united to the trunk, one arm projecting froma horizontal border of the trunk, the other arm projecting .from avertical border of the trunk.
